RIVING SPLITTER AND JACK.

Specification of Letters Patent.

Patented May 6, 1919.

To all whom it may concern Be it known that e, STANLEY HENRY and Bonner O. BALs'roN, citizens of the United States, residing at Seasidain the county of Ulatsop and State of Oregon, have invented new and useful improvements in El fling Splitters and Jacks, of which the following is a specification.

This invention is an improved appliance for splitting 10 's, especially spruce logs. the object of the invention being to provide an improved appliance of this kind embodying a splitter and a jack which may be used to gether and which also permit of the separate use of the j ack, and by means of which a log may be verv readily and uiclrly split.

.Vith the above and other objects in view, the invention consists in the construction, combination and arrangementv of devices hereinafter described and claimed.

In the accompanying drawings Figure l is a plan, partly in section, of our improved splitter and jack, showing the same arranged for use in splitting a log.

Fig. 2 is an elevation of the same at right angles to Fig. 1. I

Fig. 3 is a detail elevation of the jack showing the same removed from the splitter and in use, without the splitter, in opening the log.

- Our improved riving and splitting appliance comprises a splitter 1 and a jack 2. The splitter comprises a pair of members 3 each of which has an arm 4 and a head 5, the head being inset from the arm as at 6 and the arm being provided with an inimrdly curved end portion 7 at the end opposite the head. The members 3 are pivotally connected together by a bolt 8 which passes through alining openings in over' lapping portions of the ends 7 and hence the said ineinbersii may be opened or closed to move the heads which are adapted to be placed in a crack in a log, toward and from each other.

The jack comprises a right and left hand screw 9 which has a central polygonal portion 10 for engagement by, a wrench bar, and a pair of bearing nuts 11 each of which is closed at its outer end as at 12 and is prowopics at this patent may be obtained for vided with a cylindrical lining 13 which threaded to receive one end of the screw each bearing nut, owing to the provision of the closed outer end 12 thereof being formed with an oil cup or chamber 14 in which a suitable quantity of oil. or grease can be placed before the nut is screwed onto the screw, and hence the screw and bearing nuts are kept lubricated and the use oi the jack greatly facilitated.

The jack is arranged between the arms of the splitter with its bearing nuts engaging the inner sides of the arms and nearer re offsets 6 and after the log has been partly opened or split by means of wedges and the heads of the splitter have been inserted in the crack and the jack arranged. in place in the splitter, the screw is then turned by means of a suitable lever bar or wrench and caused to move the bearing nuts from each other and to correspondingly force the arms of the splitter apart so that the appliance serves to effectually split the log, as will be understood, the jack screw developing and apply mg great power.

jack screw may be removed from the splitter when desired and used directly in the crack of a log for further opening the log and without employment of the splitter, as shown in Fig. 3.

Having thus described our invention, we claim:

A log splitter of the class described, comprising a pair of arms pivotally connected together at one end and provided at the opposite end with inset portions and with heads for insertion in a oracle in coinbination. with a jack screw arranged between the arms and for operating the same; said jack screw comprising a right, and left hand screw, and bearing nuts on the ends of said screw, each bearing nnt being closed at the outer end. and provided with an interiorly threaded lining, open attheouter end and forming an oil cup or chamber in its interior.

In testimony whereof we ailiX our signatures.

STANLEY HENRY. ROBERT O. RALSTON.
